For Use with a Stationary Cam 
 
The CV-1 is Water Resistant, Electrical/Mechanical Contact Switches intended for use with Counter-Balanced, Vertical Sliding, Bi-Parting Freight Doors. They are Wired in Series with all of the other Door Switches in the Hoistway and the Electrical Control Circuit of the Elevator so as to produce an overall Electrical Safety Loop. In addition to this Circuit Closing System there is a Mechanical Latch which locks the Bottom Door in the Closed or Up position. Because the Bottom Door is Latch locked in the Up position it will support the Upper Door should the Door connecting chain break. The CV-1 Interlock has a Single Contact and is used with a Stationary Cam.
 
*The Interlocks are made for Right-hand or Left-hand mounting. The hand is determined by standing inside the elevator looking out. The side the lock is to be mounted (Left or Right) is the hand to be ordered.
 
Description
These Locks are mounted to the Door Frame inside the Hoistway through holes in the casting. The Casting or Housing includes the Contact making Assembly, Shafts and Cam. At the top of the housing is a Roller Arm Shaft with an Adjustable Roller Arm. A Conduit connection hole in the bottom of the housing is for wiring to the contact terminals. A Cold Roll Steel cover with gasket is provided for the housing.
 
Operation 
When the Elevator stops at the Landing, the Cam on the Elevator, Stationary or Retiring, strikes the Interlock Roller Arm opening the Lock. The lower Hoistway Door then slides Vertically Downward and the locking bar mounted on the door mechanically opens the contacts. When the door is closed the locking bar closes the contacts.
